Fig. 3 depicts the example indoor locating system 300 with access point 302 and passive ToF responsor according to some embodiment.Access point 302 can comprise one or more antenna 304 and is coupled or is connected to RF switch 306.RF switch 306 can be connected to multiple antenna 308 by independent RF cable 310.Described multiple antenna 308 can be positioned at from the equal distance of access point 302, or in the independent distance around access point 302.Position and the placement of antenna 308 can be determined by the physical environment (such as, wall, ceiling, cable distribution region) such as residing for access point 302.
Such as, each antenna 308 can comprise the passive ToF responsor that can use together with access point 302, makes the multiple antennas closing on single access point 302 provide overlay area than using overlay area that only access point 302 is possible larger.In the example present, each multiple RF cables that the only hardware needed for the existing access point installation of expansion is RF switch 306 and corresponds in antenna 308.Extra antenna 308 can to arrange from access point 302 distance equal with RF switch 306 or change distance.Antenna 308 can be placed in the minimum distance unified or variable from access point 302.Such as, each in antenna 308 can be placed between access point 302 five to one hundred meters with fixed range or various distance.
Access point 302 can be suitable for performing ToF process, and time technology of sharing can be utilized (such as between all antennas 308, circulation equal time divides round-robinequaldivisionoftime), create the multiple virtual access point in multiple diverse location or the extended area around access point 302 thus.Multiple virtual access point can comprise networking capability, or is limited to only execution ToF process or other range observations, or arranges individually, thus provides the combination in any of service.In the example described in figure 3, wherein access point 302 and three virtual access point are (namely, antenna 308) usually around equipment 312, equipment 312 can by its local antenna 304 and to be connected to the antenna 308 of access point 302 mutual with access point 302, to determine the position of equipment 312.
In this example, when equipment 312 asks fine-time to measure (FTM) process, when each independent antenna 308 or antenna 304 will in listen mode time, access point 302 and antenna 308 carry out answering equipment 312 with the time interval (such as, timeslice or multiplexed communications).The position of each antenna 308 can be determined by access point 302, or manually arranges at access point 302 place, makes equipment 312 to receive enough information to perform the FTM process with access point 302 by antenna 304 and antenna 308.In this example, receiving equipment 312 is carried out the data needed for position calculation by equipment 312.In this example, access point can determine the position of equipment 312 based on the data received at antenna 304 and antenna 308 place, to provide its position to equipment 312.
Although the passive response device embodiment described in Fig. 3 can for than optionally configure more low cost and be easier to dispose, access point 302 supports that ToF serves, and makes the existing access point not comprising ToF ability will need potentially to be reapposed; Further, because the identical resource of all antennas 308 shared access point 302, along with more antenna 308 is added, the quantity of the potential client that access point 302 can be served reduces.

Such as, communication hardware can be arranged to utilize Wi-Fi agreement (such as, in IEEE802.11 standard).Except responsively device performs except ToF, active ToF responsor (408A, 408B, 408C), the network equipment 402 also just can expanded by responsor wirelessly controls.Such as, connecting (410A, 410B, 410C) can be wired or wireless connection.
As depicted in figure 4, active ToF responsor some advantage on optional configuration can comprise such as: active ToF responsor can be unusual low cost and be easy to dispose, because do not need network to connect (such as, for responsor, only needing power supply); The main access point (such as, the network equipment 402) be expanded does not need to support ToF agreement; Or the quantity of the client device that main access point can be served (such as, equipment 414) can not as in passive ToF responsor method depicted in figure 3 by limit.
Fig. 5 A depicts the example with the communication system 500 of access point 502, passive repeater 504 and one or more active extender 506 according to some embodiment.In this example, by using mass-rent (crowed-sourcing) ability, one or more other ToF responsors 508 can also be utilized independent of access point 502.Such as, communication system 500 can be included in the fixing ToF responsor 508 of concentrated (centralized) position.Fixing ToF responsor can not have its more specific location information of configuration.In this example, the installation of responsor does not require that the position of responsor is accurately determined, and can when performing without any when special expertise or information.
In this example, server 510 (such as, the access point server 214 of Fig. 2) ToF responsor 508 and access point 502 can be connected to, and be configured to collect the measurement from the one or more equipment 512 mutual with fixing ToF responsor 508, and determine the position of fixing ToF responsor 508 thus, and get involved without any user.Equipment 512 can by being such as the server 510 that any available wireless connection of WiFi or cellular network (3G, 4G, LTE etc.) visits network (such as, the Internet).ToF responsor 508 self does not need the Internet architecture as the connection provided between server 510 and equipment 512.
In this example, be suitable for realizing indoor positioning technologies receiver can for portable radio communication device (such as, equipment 512) a part, such as personal digital assistant (PDA), the laptop computer with wireless communication ability or portable computer, net basis, wireless telephone, wireless handset, pager, instant messaging device, digital camera, access point, TV, Medical Devices (such as, heart rate monitor, blood pressure monitor etc.) or can wireless receiving and/or send other equipment of information.
Fig. 5 B is the process flow diagram of diagram according to the exemplary method 550 of the position for automatically determining ToF responsor of some embodiment.In this example, described method 550 can be performed by the ToF responsor 508 of Fig. 5 A.
At 552 places, the network equipment (such as, ToF responsor 508) can be asked from equipment (such as, the equipment 512 of Fig. 5 A) receiving position ToF.ToF request in position can comprise the exchange of grouping or message, with the distance measured or between computing equipment and the network equipment.Ask in response to receiving position ToF, the network equipment can send a location request to server (such as, server 510) at 554 places.Position requests can be included in the distance determined by the network equipment between commutation period.Position requests can comprise the request of the position to the network equipment.
At 556 places, the network equipment can receive the position request response from server.Position request response can comprise the position of equipment, the position of the network equipment or both combinations or can in positioning equipment or any additional information setting up auxiliary network equipment in secure connection process between equipment and the network equipment.At 558 places, at least in part based on the information received from server by the network equipment, the network equipment can determine the position of equipment fatefully.At 560 places, the network equipment can send the position ToF comprising device location and respond equipment.
Although sequentially arrange in the example of Fig. 5 B, other examples can reorder to operation, ignore one or more operation and/or the single processor that uses multiple processor or be organized as two or more virtual machines or sub-processor carrys out two or more operations of executed in parallel.In addition, other examples still can be embodied as one or more concrete interconnected hardware or integrated circuit modules by operation between the modules and by the relevant control of module communication and data-signal.Thus, process stream can be applicable to software, firmware, hardware and mixing realization arbitrarily.
